Voice UI for the Blind

Mobile Voice UI Design Mole-bile Voice started out as an exploratory project for identifying and solving a blind users’ need. Through user research, we discovered that many blind smartphone users experienced difficulties navigating their phones. We designed two voice UI mobile application that explored blind user friendly interfaces (scan QR codes below for details):

VUI Development ToolWe want to encourage more designers and developers to experiment with and create voice UI mobile applications, but we were not able to find an easy to use VUI mobile app development tool. So, we made one!

We conducted usability testing on the designs and concluded that voice UI holds promise as an alternative smartphone navigation method for blind users, especially those with lower technology familiarity.

Mole-bile Voice provides a drag-and-drop graphic user interface where designers/developers can create versatile conversation flowcharts for their voice apps, and then this flowchart would be automatically converted into code and easily deployed as a smartphone app.
